    Abstract: A display tube comprises an electron source (10), a module (20) provided with a guidance cavity (25R, 25G, 25B) for guiding electrons emitted by the electron source (10) to an exit aperture (27R, 27G, 27B) of the guidance cavity (25R, 25G, 25B) and beam-shaping means (30) for forming an electron beam (EBR, EBG, EBB) from guided electrons leaving the exit aperture (27R, 27G, 27B). The electron beam (EBR, EBG, EBB) travels towards a display screen (3). The beam-shaping means (30) are arranged to change a direction in which the electron beam (EBR, EBG, EBB) leaves the guidance cavity (25R, 25G, 25B) in accordance with a predetermined application. For example, the electron beam (EBR, EBG, EBB) is deflected to realize gun pitch modulation in the electron gun of a cathode ray tube. As the electron beam is deflected near the exit aperture (27R, 27G, 27B), spot errors are reduced and the display tube has a relatively high image quality.

    Abstract: A display device has a display screen (130) comprising a first array of picture elements (135) for displaying image information, and cathode means (120) for emitting electrons. The picture elements (135) are grouped together in sub-arrays (132). The emitted electrons are collected by an electron concentrator (115) which redistributes the electrons into a homogenous electron beam (EB). A single electron concentrator (115) is present for each sub-array (132) of picture elements (135), and the display device has selection means (140) for deflecting the electron beam (EB) leaving an electron concentrator (115) to any picture element (135) of the corresponding sub-array (132). Thereby, the displayed image may have a relatively high resolution. In a preferred embodiment, the image brightness is particularly high and variations in brightness uniformity over the displayed image are reduced.
